.TH "x86info" "1" 
.SH "NAME" 
x86info \(em display x86 CPU diagnostics 
.SH "SYNOPSIS" 
.PP 
\fBx86info\fP [\fB-a\fP]  [\fB-c\fP]  [\fB-f\fP] [fB-F\fP]  [\fB-m\fP] [\fB-mhz\fP]  [\fB-r\fP]  [\fB?\fP]  [\fB--all\fP]  [\fB--cache\fP] [\fB--flags\fP] [\fB--verbose\fP]  [\fB--msr\fP]  [\fB--mhz\fP]  [\fB--registers\fP]  [\fB--help\fP]  
.SH "DESCRIPTION" 
.PP 
This manual page documents \fBx86info\fP, a 
program which displays a range of information about the CPUs 
present in an x86 system. 
.PP
In order to make full use of this program you need to have the CPU ID
and MSR device drivers in your kernel with accessible device files
/dev/cpu/<n>/cpuid and /dev/cpu/<n>/msr.
.SH "OPTIONS" 
.PP 
This program follows the usual GNU command line syntax, with 
long options starting with two dashes (`-').  A summary of options 
is included below. 
.IP "\fB?\fP           \fB--help\fP         " 10 
Show summary of options. 
.IP "\fB-a\fP           \fB--all\fP         " 10 
Show all information.  Equivalent to 
\fB-c\fP \fB-f\fP \fB-m\fP 	    \fB-r\fP \fB-mhz\fP.  
.IP "\fB-c\fP           \fB--cache\fP         " 10 
Show TLB, cache sizes and cache associativity. 
.IP "\fB-f\fP           \fB--flags\fP         " 10 
Show CPU feature flags. 
.IP "\fB-m\fP           \fB--msr\fP         " 10 
Dump model specific registers.  This feature is currently only 
supported on a few different processors. Future versions will
include parsing of bits in MSRs for all processors.  
.IP "\fB-mhz\fP           \fB--mhz\fP         " 10 
Estimate current clock rate. 
.IP "\fB-mp\fP            \fB--mptable\fP       " 10 
Dump MP table showing CPUs BIOS knows about.
.IP "\fB-r\fP           \fB--registers\fP         " 10 
Show register values from all possible cpuid calls. 
.IP "\fB-s\fP           \fB--show-machine-check\fP         " 10 
Show machine check exception information.
.IP "\fB-v\fP           \fB--verbose\fP         " 10 
Show verbose descriptions.
